It would be pointless to release a feature that works only for non-relevant content.

There are people out there who haven't reached Exalted with those factions on either their main or alt, also a freshly dinged character still has use of the factions because of their ilvl gear to make LFR available.

It doesn't fix anything as long as it is "bonus" rep. There needs to be a way to earn rep from dungeons that shares a daily cap with dailies. This way there will be only way to make dailies truely optional.

As for the new Valor items faction. It will be related to the new Raid and Blizzard said yesterday that It wont be like ICC where you just kill a bunch of trash. Likely the new FL from of gated rep grind.

pointless future? pet battles perhaps imo? but not these factions.

I didnt mean the feature is pointless, I meant that it would be pointless to make it work ONLY with 5.1 reps.
